Paint ikozvino inonyanya kukamurwa kuva mafuta-based pendi uye mvura-based pendi, uye musiyano mukuru pakati pavo ndewekuti pendi yemvura inonyanya kushamwaridzana kupfuura pendi yakagadzirwa nemafuta. Ko kunamatira kwependi yemvura kuchave kwakaipisisa kupfuura kwependi yakagadzirwa nemafuta here? Ndezvipi zvikonzero zvekukanganisa kusungirirwa kwependi yemvura? Chii chingaitwa nezvazvo?

Pane zvikonzero zvakawanda zvinokanganisa kunamatira kwependi yemvura:

① Iyo substrate haina kunyatsocheneswa, uye guruva nemafuta zvinoramba zviri paworkpiece kana kuti hazvina kunyatsokwenenzverwa.

② Iyo substrate yekuvaka haina kukodzera, uye kusarudzwa kweprimer haina kukodzera mvura-based topcoat.

③ Kwete kuoma zvachose mushure mekupfapfaidza

Mhinduro dzekuvandudza kunamatira kwependi yemvura ndeiyi inotevera:

① Dura uye bvisa mafuta kubva mu substrate usati wagadzira primer. Kune iyo workpiece ine nzvimbo yakatsetseka, zvinodikanwa kunyatso puruzira kumusoro kuti iwedzere uye wozoita kunotevera kuvaka.

② Paunenge uchishandisa pendi yemvura, sarudza primer inokodzera pendi yemvura, pane kupfapfaidza pendi yemvura-yakavakirwa pamusoro nemafuta-based primer.

(3) Pendi yemvura-yakavakirwa pendi sependi inoomesesa yemvura-yakavakirwa pendi, kusungirirwa kwayo kucharatidza mhedzisiro dzakasiyana nedhigirii yekuomeswa yefirimu pachayo, zviri nani kuomeswa, kusimba kwekunamatira, mushure mekupfapfaidza kuve yakaoma zvachose pamberi peiyo firimu. danho rinotevera mukushanda kwekuvaka, yakakodzera inogona kupisa kana kupisa mhepo kuomesa.

Iko kunamatira kwependi yemvura haina kusimba zvakakwana, tsvaga chikonzero uye wochigadzirisa. Zvechokwadi, kusati kwatengwa kwekunzwisisa kwakarurama kwemaitiro uye sarudza pende yakakodzera yemvura-based kuitira kuti udzivise zviri nani mamwe matambudziko anotevera.
